I'm trying to determine whether a Harmony 676 will fit my needs. The Logitech web site is surprisingly high on fluff, low on info. I took their little test drive thing, and it was most unsatisfactory--just activities setup? How much other customization can you do on the thing? For example (the biggest draw for my wife) I'd like to be able to press Mute on the remote, which will mute BOTH the TV and the receiver. The TV mute is because that turns on closed captioning. Of course, a button that just turns on closed captioning in TiVo and DVD mode would work just as well. Does anyone have a PDF manual for the thing or anything like that?
